This course aims to teach learners how to fuse I/O operations using CISCOps in firmware file systems. The learning outcomes include understanding how FusionFS leverages near-storage computational capability to reduce I/O bottlenecks, introducing the concept of CISCOps to combine multiple I/O and data processing operations, implementing MicroTx for crash consistency and fast recovery, and exploring scheduling techniques for efficient resource utilization. The course covers topics such as storage hardware and software trends, common I/O sequences in applications, FusionFS components, crash consistency for CISCOps, and evaluation goals. The teaching method involves presenting state-of-the-art designs, discussing the RISC vs CISC operations debate, providing examples of FusionFS I/O processing, and evaluating performance gains through benchmarks and real-world applications. This course is intended for individuals interested in firmware-level file systems, storage optimization, and improving I/O performance in computing systems.
